I am landing at Frankfurt late at 10+ pm. Thinking to rest for a night before continue the land transit to destination. Any idea what is the value for money hotel that I could stay for a short night? Of course with all my luggages.
There's a Hilton Garden Inn directly connected to the airport (FRA, let us know if you're going to HHN), which you could consider.
It's also a 12 minute trip by train from FRA to the city's main train station, which has connections all over the city, so you could use any hotel booking site to find a hotel in the city near public transit that meets your personal definition of "value for money." You could also give thought to where your land transit leaves from.
Hilton and Sheraton are right in the airport. There are cheaper offsite locations very close by, but you will need to use their shuttle. For example for a midweek night next week, you'd pay around $130 for Sheraton or Hilton and offsite locations could be less than $80 (Ibis, Moxy, Park Inn Radisson)
If you go offsite, I would recommend contacting the hotel up front about shuttle instructions (pick up point, schedule, number to call, etc.). The airport is huge and fairly convoluted.
Stating the obvious: Typing "Frankfurt Airport Hotels" into Google will give a great overview of choices, prices and locations for any given date.
